Application filed March 3, 1911. Serial No. 812,028.

To all whom it may concern:

Be it known that I, ULYSSE DAUBRESSE,

a citizen of the United States, residing at Novinger, in the county of Adair and State of'Missolirhhave invented certain new and useful Improvements in Acetylene-GasGenerators, of. which the following is a specification. p

My invention relates to improvements in lamps, and has for its leading object the rovision of an improved form of acety ene lamp particularly adapted for miners use.

A further object of the invention is the provision of an improved water feed for acetylene lamps which will insure the water descending into the carbid chamber in such manner as to thoroughly dampen all portions of saidcarbid instead-of merely one limited portion adjacent the drip'valve.

Another object of my invention is to provide a miners lamp having an improved water feed and an improved burner for the gas and means for readily cleaning the said burner and for. securing the burner cleaner to the lamp when not in use.

Other objects and advantages of my invention will be apparent from the following description taken. in connection with the drawings, and it will be understood that I may. make changes in construction lying within the scope of my claim without departing from the spirit of the invention.

Figure 1 represents a side elevation of my complete lamp. Fig. 2 represents a front view thereof. Fig. 3 representsa plan view igl. 4 represents a vertical sectional view of t e complete lamp: Fig. 5 represents a plan view of the novel burner cleaner, and, Fig. 6 represents a sectional view of the. burner removedwiththe cleaner in operative position therein.

-In the drawings, the numeral l designates the cylindrical casing of my lamp, having the slightly rounded cover portion 2 soldered to the upper end, said cover section having the flange 3' rising from the middle portion thereof around the filling opening 4, while hinged to the bracket 4 adjacent said flange is the supplemental cover section 5 having a depending flange 6 fitting. in and making tight engagement with the flange 3 to retain the cover 5 in closed position.

Secured in the casing 1 intermediate the length thereof is the partition 7 which divides the casing into the compartments 8' and 9 entirely isolated from each other. Formed in the partition is an opening 10 having depending therebelow the tube 11 which projects into the compartment 3,

while projecting through the cover 2 is the rod 12 which asses through the compartment 8 and tu e 11 and bears on its lower end the valve 13 adapted "to seat against the lower end of the tube to close the passage from the compartment 8 to the compartment 9. An internally threaded tube 14 surrounds the upper end of the'rod 12 and an externally threaded sleeve 15 engages the threads of the tube, said sleeve having the head 16 with a slot 17 formed in one side in which the laterally bent end 18 of the rod 12.

is normally contained. The operation of this valve will be readily understood and it will be seen that when the compartment 8 is filled with water and the sleeve 15 is screwed upward to force the rod upward and hold the valve against its seat no water can pass down through the tube 11 into the lower portion of the casing, while as the sleeve is screwed down the valve will move away from its seat to allow a greater or less amount of water to pass into the compartment 9. When it is desired to quickly shut oi? the amount of water passing through the tube or to entirely check said How of water, I raise'the bent end 18 of the rod out of the slot and'partially turn-the rod to cause said end to rest on the top of the head, whereby the rod will be 'held in elevated position to seat the valve. p

A flaring base flange 19 is secured to the lower end of the casing 1, said flange extending a short distance inward" and having rising therefrom the interiorly threaded sleeve or ring-20 providing a space 21 between said sleeve and the inner face of the casing. the threaded neck 22 of the carbid receptacle 23 which forms the bottom of the lamp,

there being a groove! 24 formed at the base onto said packing and running around Engaged by said threaded-sleeve is ,bidchamber I mount-on the partition the' thereon as a wick. The neck 22 of the carbid receptacle has a reduced plain portion 27 projecting upward beyond the wick 26, a plurality of openings 28 being formed in the portion 27 to allow the Water from the wick to seepv down through the openings into the carbidv receptacle. To form'a closure for the top of said receptacle through which the gas can pass I mount in the portion 27 above the o-penings'28 the felt pad 29, a plate 30 being secured to the pad and extending across the neck and, having an inverted V -shaped portion 31 at each end hooking over the portion'27, a handle 32 being secured to the plate 30 to raise and lower it and its attached pad.

To receive the gas generated in the car- T-shaped tube having the head 33 with one of said head is closed to preventthewater the casing of rawwool is secured in the head tube 33 ing the central opening 37 and having the end open and projecting of the carbid chamber while the upper end from entering the .tube. Lying along the partition in the chamber water tight joint with tube 34 having its free'end projecting from 1. A wick member 35 preferablyand depending into the chamber 9," while inserted in the outer end of the tube 34- is the smaller end of the lead burner 36 havferrule 38 on its outer end, said burner tip being forced intothe tube until the tubecuts into the lead when a gas-tight 'joint willbe formed. a

From the foregoing description taken in connection with the drawings the construction of my improved lamp will be readily understood and it will be seen that when the carbid and water chambers are filled the opening oi the valve 13 will permit the water todrip down upon the asbestos wick member, whence it will seep through the openings in the neck of the carbid chamber into said chamber to combine with the carbid and produce a combustible gas. Said gas then passes up through the felt pad, the wick 35 and the L-shaped passage formed by the tubes and then ing in the burner tip.

Formed on the burner "tube is the abutment shoulder 39,:and to increase the brilliancy of the light given by the lamp and 'focus the same ll-mount on the end of the burner tube the curved reflector 40 having its longitudinal diameter of greater length than its lateral dimension and having the sockets 41 formed at each end, the shoulder on the tube limiting the rearward movement through the partition just above the portion error the neck 8 and makingthe head is the burner I out through the open-Y ncense of the reflector. To secure thereflector in position and toat the same time facilitate the removal thereof when desired, 1 secure to the front of the casing 1 the spring latch 1nember42, the reflector being mounted on the tube with its shorter diameter parallel to the axis of the casing and then rotate the reflector a quarter turn, the rotation of the reflector bringing its wider portion against the latch member which isf'forced outward,

the end of the reflector being engaged under the latch which 'fitsintothe socket 41 at the lower end to secure the reflector in position. ;T Mounted on the-burner tube at-the rear of the reflector is the circular plate 43 having a "central opening :44 to receive the burner tube and having a recess or slot formed in one side elfv slightly greater width than the diameter or the wider end of the burner 36,

a pin orfsteel wire member 45 being secured to the; plate 48 and projectingtherefrom centrally of andv bisecting the slot therein.

lln use, when the burner becomes clogged and retu'ses to burn well; I. remove the reflector and thenslide ofl the plate audien- ,gage the burner tip in the slot in the plate,

the pin 45' pa'ssinginto the hereof the tip and servingto clear out the obstruction. It,

will thus be seen that the reflectorand its latch serve,afdouble-functioIi in that they act not only as a reflector and lock therefor I l but serve to retain; the cleaner in position when not in 'use whlle permitting of the ready removalb'the'reot when desired. litis also apparent that-ll have provideda simple, durable and eflicient lamp which when employed for miners use'may be equipped with the hat hook t6 which will fulfil all the objects of the invention in-a most satisfactory manner. lclaimi" A lamp of the class described, comprising a base for containing carbid, a threaded parser: pauhnnssn Witnesses VICTOR Bnooem, A, R.
